Grömitz in the rain: 15 things to do on a wet day

Diesen Artikel auf Deutsch lesen

In short

When it rains in Grömitz, head for the Grömitzer Welle seawater pool and sauna (Kurpromenade 58), the diving gondola on the pier (€9 for adults), the EasyJump trampoline park or the Cine Event Center. Further afield: Cismar Abbey, the Haus der Natur shell museum with over 4,000 species, Sea Life Timmendorfer Strand and Lübeck's old town.

How often does it actually rain?

Statistically Grömitz has ten rain days in each of July and August – which sounds like a lot but usually means a twenty-minute shower followed by sun. Genuine all-day rain is rare. Still, when it comes it usually comes with wind, and a plan beats a debate over breakfast. More numbers in our climate table.

Seven ideas in Grömitz itself

  1. Grömitzer Welle, Kurpromenade 58 – 1,000 m² of water holding 1.1 million litres of treated seawater, a wave pool with waves up to a metre, nearly 70 metres of slides, a lazy river, a baby area and outdoor pools looking over the bay. Water temperature 27–33 °C, and reduced entry with the ostseecard.
  2. The sauna area at the Grömitzer Welle – panorama saunas with a sea view plus the sauna lounge. The best argument for a wet afternoon without children.
  3. Diving gondola on the pier – in rain but calm seas, a direct hit: €9 for adults, €6 for children up to 15, about 30 minutes underwater. Closed in storms. See our pier article.
  4. Dünenwelten, Kurpromenade 6a – indoor play world for younger children.
  5. EasyJump trampoline park, Grömitzer Höhe 3 – the most efficient way to burn off energy. Easyfitness for adults is next door.
  6. Cine Event Center, Kirchenstraße 27–29 – the local cinema, small and current.
  7. Strandhaus, Kurpromenade 20 – coffee, cake and a view of the grey sea. An underrated category: watching rain from indoors.

Opening hours and prices change – a quick look at the relevant website before you set off saves a wasted trip. More on these in day trips from Grömitz.

Rainy days with children

The reliable order by age: up to 6 Dünenwelten and the Grömitzer Welle baby area; 6 to 12 wave pool, slides, EasyJump and the diving gondola; 12 and up bowling in Sierksdorf, cinema, Lübeck.

One tip that always works for us: Hansa-Park in Sierksdorf (25 minutes) is far emptier in light rain than usual, and most rides keep running. Pack a poncho and spare clothes in the car and you get the park nearly to yourselves.

A wet day for two

Our own routine for a rainy day: sauna at the Grömitzer Welle in the morning, a fish roll on the promenade at lunchtime, Cismar Abbey and the abbey café in the afternoon (April to October, Wed–Sun 11am–5pm, home-made cake), then cooking with a view of the bay in the evening. For restaurant choices see eating in Grömitz.

Around Cismar there are also artists' studios – ceramics, jewellery, photography, textiles. An afternoon of browsing with no schedule.

If you still want to go outside

Honestly: a Baltic storm walk is one of the better reasons to come here at all. In a decent rain jacket, the empty beach in wind and surf is more impressive than any sunny day.

  • The cliffs north of Grömitz – spectacular in an onshore wind, but keep well back from the edge.
  • Amber hunting – best odds along the tideline after a storm with onshore wind, especially in the morning.
  • The marina – a good place in wind to hear the rigging clatter, then thaw out in the harbour restaurant.

And if nothing else appeals: the 27 m² roof terrace has a covered section. Watching rain with a coffee counts as a plan too.
